Title: Narrow pulse width detecting circuit
Inventor: SUETSUGU KAZUAKI
IPC: G01R13/28
Filed: 1987-10-21
Abstract: PURPOSE:To accurately detect a pulse with narrow pulse width by selecting an input pulse signal and the signal generated by delaying it by a delay element alternately and generating pulses having the same width as that of the signal at the delay time, and sampling those pulses when the pulse signal falls. CONSTITUTION:The output of the delay element 10 is delayed a time T1 behind the input pulse signal IN. When the output Q of a D type FF 12 is to fall to a low level first, a selection part 11 selects the signal IN. When the signal IN rises, the FF 12 is triggered and its output is inverted, so that the selection part 11 selects the side of the element 10. Consequently, the selection part 11 outputs narrow-width pulses in synchronism with the rising of the signal IN. The signal IN, on the other hand, is compensated by the delay of the selection part 11 and FF 12 through a delay element 132, inverted by an inverter 133, and inputted to the clock terminal of a D type FF 131. The FF 131, therefore, samples the output Q of the FF 12 in synchronism with the falling of the signal IN. Thus, only pulses of the signal IN whole pulse width is shorter than the timer T1 of the element 10 are detected.

Title: Piezoelectric printing element
Inventor: YAMADA HIROAKI
IPC: B41J2/295
Filed: 1985-11-25
Abstract: PURPOSE:To obtain a small high-efficiency piezoelectric printing element by using a displacement/enlargement mechanism using a liquid and a lamination- type piezoelectric element. CONSTITUTION:A container 3 forms two cylinder chambers which are separated right and left by a piston 6 through connexion with the container 2. In the left cylinder chamber, a piezoelectric element 5 is stored, while in the right cylinder chamber, a liquid 7 is packed. If a voltage is applied to the piezoelectric element 5 from a lead wire 4, the piezoelectric element 5 expands, pushing the piston 6. If the piston 6 is pushed, a pressure is applied to the liquid 7 and the tip of wire 1 is pushed out of the container 2, resisting the restoration force of a spring 8, thus printing the surface of recording paper. The displacement/enlargement factor A of wire 1 against the displacement of the piezoelectric element 5 is represented by the following expression: A=D<2>/d<2> where the diameter of wire is (d) and the inner diameter of the piston 6 is D. If, for instance, the diameter (d) of wire is 0.2mmphi, the diameter of the piston 6 may have only to be approx. 2mm, even if the displacement/enlargement factor were considered 100 times.

Abstract: PURPOSE:To prevent the formation of creases on a document because of the distribution of revolution speed of a motor and the slip between a conveyor belt and the document by transporting the document in pulled state by making the transport speed on the receiving side always higher.

Title: Electrode structure of object detector
Inventor: IEDA SEIICHI
IPC: G01D5/241
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To make a larger ground electrode than a detection electrode in a lower end to prevent a detour of an electric field for the ground electrode from the detection electrode, by lessening a lower end for the detection electrode to the ground electrode. SOLUTION: Two electrodes 10a, 10c are housed in housings 11, 12 in a basically opposite state. The detection electrode 10a for performing object detection is covered on the ground electrode 10c in cross section substantially U-shape in the Y direction so as not to take in the impedance change of a directional component (except for X direction) unnecessary for object detection. The impedance change of the directional change unnecessary for detection is added by providing a curvature part in the Y direction and it is possible to expand a detection range. In addition, the lower end of the detection electrode 10a is lessened for the ground electrode 10c. In other words, the detour of the electric field to the body side of a vehicle can be prevented by making the larger ground electrode 10c than the detection electrode 10a in a lower end.
